Planning and building regulation drawings in Fulham (SW6)

SW6 is built on rows of late-Victorian terraces, and that pattern shapes almost every drawing we produce for it. Walk the streets off New Kings Road or around the alphabet roads and you find the same rhythm repeated: narrow plots, consistent frontages, and back gardens just deep enough to tempt an owner into a rear extension. The Peterborough Estate's ornamental "Lion Houses" sit at the grander end of that stock, with the Edwardian mansion blocks near Parsons Green offering a different set of questions entirely, mostly about leasehold consent rather than planning permission itself.

Closer to the river, Sands End tells a slightly different story. Artisan terraces around Hugon Road and Breer Street stand alongside the newer Imperial Wharf flats, so the work here splits between traditional house extensions and flat alterations governed as much by the freeholder as by the council. Whichever part of SW6 you're in, side-return depth, party-wall boundaries and the character of the surrounding streets tend to decide what a scheme can achieve before a single drawing is started. We work through those constraints against your actual address rather than assuming what applies borough-wide.

Planning in Fulham: what to know before you apply

Hammersmith & Fulham reviews basement proposals against its own basement policy, which means most below-ground schemes need a basement impact assessment before validation, not after. That matters across SW6 because deep single- and multi-storey basements are common on the borough's terraced plots, and the council checks structural and drainage impact on neighbours as closely as it checks the planning principle. Design control tightens further inside a conservation area, where rooflines, frontages and materials are all assessed against the existing street pattern rather than left to the applicant's preference. Some parts of the wider borough also carry an Article 4 direction removing permitted development rights for HMO conversions, and a further direction reaches into conservation areas to cover certain basement and frontage works that would otherwise need no application. None of this is uniform across SW6, so we check the designations on your specific plot before we draw anything, then design to what your address can actually support.

  • A single-storey rear extension up to 4 m deep on a detached house, or 3 m on any other house, is Class A permitted development subject to the height and materials conditions.
  • An Article 4 direction applies here and may withdraw this freedom — the schedule must be checked before relying on it.
  • One or more constraints are unknown — we check the council's registers as part of the free appraisal.
  • Where permitted development applies, a lawful development certificate proves it for lenders and buyers.

FAQ

Fulham (SW6) — FAQs

Do I need planning permission for a side-return extension in Fulham?+
It depends on the plot and, just as often, on whether the house sits inside one of Fulham's conservation areas. Outside a conservation area, a modest side-return infill can sometimes proceed under permitted development, but the tight, consistent terraced plots typical of Fulham mean depth, height and the roofline all get checked against neighbouring properties. Once a conservation area boundary is involved, the permitted development route narrows considerably and a full application becomes the more reliable path. We confirm which situation applies to your address before recommending a route.
Can I dig a basement under a house near Parsons Green?+
Yes, but Hammersmith & Fulham's basement policy applies regardless of which part of SW6 you're in, and a basement impact assessment is expected alongside the planning application. Around Parsons Green that policy sits on top of conservation area controls covering frontages and rooflines, so the surface-level design of the house matters just as much as the engineering below ground. Party-wall agreements with neighbours on these deep terraces usually run in parallel with the planning process rather than after it, so it's worth starting both early.
